A Staten Island mom allegedly whacked her baby daddy over the head with a cooking pot yesterday — because she was furious that he hadn’t bought her a Mother’s Day gift.

“I hit him with a pot, and I’m glad I did!” a steamed Aretavia Kimbrough, 28, allegedly told cops after nailing boyfriend Charmean Allen, 28, with the pot, leaving him with a 4-inch gash and a big lump on his head.

“I’ve been with him for seven years, and he never bought me nothing! ”

But Allen, who has an 8-month-old son with Kimbrough, later insisted to The Post, “I was going to get her balloons and candy and take her to dinner.

“But I can’t take her to dinner because the police aren’t releasing her.”

With his head still wrapped in bandages, Allen added, “She has a little bit of a temper, I’d say. This is probably the end for us. But I’ll take care of my kid.”

Allen said Kimbrough woke him in their Stapleton apartment at around 7 a.m., demanding to know what he had bought her to celebrate her first Mother’s Day as a mama. He immediately realized he was in trouble.

Kimbrough was holding their son, Charmean Allen Jr., in one arm — and a large pot, “the kind you cook corn in,” in her other hand, he said.

As he tried to explain that he had hoped to purchase gifts and take her to dinner, she walloped him on the head with the pot, and then stormed out of the room, Allen said. The wounded boyfriend said he called a friend on the phone to get help. The pal then called 911, Allen said.

When police and EMTs arrived, Charmean told them that he did not need to go to the hospital and that he didn’t want to press charges against Kimbrough.

But cops arrested the “crazed-looking” mom anyway.

Kimbrough is expected to be arraigned on domestic-violence charges today, law-enforcement sources said.
